Z' Reservation at LEP2

G. Montagna, O. Nicrosini, F. Piccinini +2

We consider the possibility that one extra $Z \equiv Z^{'}$ exists with arbitrary mass and fermion couplings that do not violate (charged) lepton universality. We show that, in such a…

Properties of equations of the continuous Toda type

E. Alfinito, G. Profilo, G. Soliani

We study a modified version of an equation of the continuous Toda type in 1+1 dimensions. This equation contains a friction-like term which can be switched off by annihilating a fr…

Four-Loop Perturbative Expansion for the Lattice $N$ -Vector Model

Sergio Caracciolo, Andrea Pelissetto

We compute the four-loop contributions to the $β$ -function and the anomalous dimension of the field for the $O (N)$ -invariant $N$ -vector model. These results are used to compute the…

Squeezed Neutrino Oscillations in Quantum Field Theory

E. Alfinito, M. Blasone, A. Iorio +1

By resorting to recent results on fermion mixing which show that the Fock space of definite flavor states is unitarily inequivalent to the Fock space of definite mass states, we di…

Anomalous $Z^{'}$ effects in the WW channel at NLC

P. Chiappetta, F. M. Renard, C. Verzegnassi

We consider the virtual signals of a $Z^{'}$ of very general type in the process $e^{+} e^{-} \to W^{+} W^{-}$ at a future linear collider (NLC). We show that possible deviations from the SM pre…

Duffin-Kemmer-Petiau equation on the quaternion field

Stefano De Leo

We show that the Klein-Gordon equation on the quaternion field is equivalent to a pair of DKP equations. We shall also prove that this pair of DKP equations can be taken back to a…

Quaternion Higgs and the Electroweak Gauge Group

Stefano De Leo, Pietro Rotelli

We show that, in quaternion quantum mechanics with a complex geometry, the minimal four Higgs of the unbroken electroweak theory naturally determine the quaternion invariance group…

Topological Field Theory and Nonlinear $σ$ -Models on Symmetric Spaces

L. Martina, O. K. Pashaev, G. Soliani

We show that the classical non-abelian pure Chern-Simons action is related to nonrelativistic models in (2+1)-dimensions, via reductions of the gauge connection in Hermitian symmet…

Quaternions for Guts

Stefano De Leo

We derive an appropriate definition of transpose for quaternionic matrices and give a new panoramic review of the quaternionic groups. We aim to analyse possible quaternionic group…

Is the galactic halo baryonic?

F. De Paolis, G. Ingrosso, Ph. Jetzer +1

Recent observations of microlensing events in the Large Magellanic Cloud suggest that a sizeable fraction of the galactic halo is in form of MACHOs with mass less than abou 0.1 M_{…

Mean-field description of nuclear charge density distributions.

R. Anni, G. Co'

We propose a method to extract nuclear charge distributions from elastic electron scattering data based upon a mean field approach. The nuclear charge distributions are generated b…

Integrable nonlinear field equations and loop algebra structures

E. Alfinito, M. Leo, R. A. Leo +2

We apply the (direct and inverse) prolongation method to a couple of nonlinear Schr{ö}dinger equations. These are taken as a laboratory field model for analyzing the existence of a…
